Definitions
- the invention relates to a slide ring seal assembly, particularly a seal assembly for running gears.
- the seal assembly is composed of two, back-to-back arranged, cross-sectionally angled (L-shaped) slide rings whose axially extending legs form a seat for a stationary, cross-sectionally generally trapezoidal, resilient sealing body.
- the sealing bodies are secured against displacement by depressions provided in the outer upper surface of the legs.
- Slide ring seal assemblies are used on shafts and axles and are inherently exposed to substantial soiling.
- Exemplary structures in which the slide ring seal assemblies may be used are drive axles of construction machinery or track-laying vehicles which are continuously exposed to sand, dust, mud and the like.
- Slide ring seal assemblies, particularly running gear seal assemblies where the slide rings have a cross-sectionally angled configuration often have cross-sectionally trapezoidal, spring-washer-shaped sealing bodies in which the slide rings are elastically supported.
- the annular sealing bodies which act as springs take over the function of the axial sealing pressure, the static seal between slide ring and seating bore and the frictional torque transmission.
- the axial force required for ensuring a seal is obtained by upsetting the elastic sealing body between the slide ring and its seating bore as the seal is stressed to assume its dimensions in the installed state. Particularly upon frictional torque transmission and distortion of the sealing body during installation or service, often malfunctioning and breakdown of the sealing properties are experienced.
- a known slide ring seal assembly of the above-outlined type is described, for example, in German Patent No. 197 53 918.
- This patent describes a slide ring seal assembly having annular, cross-sectionally trapezoidal sealing bodies which are disposed between the axial legs of the slide rings and the seating bore. At the contact faces of the slide rings frictional torques appear which are transmitted by the sealing body to the housing. By virtue of the different distances from the axle center and thus from the null-line of the frictional torques, different forces in the supported surfaces of the sealing bodies appear. Thus, a relatively large force is obtained because of the short distance (leverage) to the outer upper face of the axial leg of the slide ring.
- the frictional torques are conventionally transmitted by the surface pressure to the supporting surfaces of the sealing bodies. Due to the relatively high force effect on the outer upper surface of the axial leg of the slide ring, often the sealing body rotates with respect to the slide ring. Such a rotation causes a breakdown in the seal and thus renders the slide ring seal assembly defective.
- U.S. Pat. No. 4,421,327 describes a slide ring seal assembly which includes a securing arrangement for preventing rotation of the sealing body.
- the forces on the upper surface of the axial leg of the slide ring are additionally taken up in a form-fitting manner by depressions provided therein.
- the sealing body thus can transmit significantly larger frictional torques.
- Such structures involve the risk that the axially outer sealing body is twisted during dynamic stresses or even already in its installed state. As a result of such twist, the sealing body lifts off the radially outer upper surface of the slide ring leg, whereby a gap is formed between the slide ring leg and the sealing body. Dirt or lubricating oil may gain access to such a clearance.
- the function of the slide ring seal assembly and the transmittable frictional torques are not optimal.
- the slide ring seal assembly includes a slide ring having an axially extending annular leg.
- the leg has radially outer and radially inner circumferential surfaces and a free axial end surface.
- a plurality of circumferentially spaced recesses are provided in the leg and extend axially inward from the free axial end surface. Each recess extends from the radially outer surface to the radially inner surface.
- An annular sealing body surrounds the leg and is seated thereon. Circumferentially spaced, radially inward-oriented extensions forming part of the annular sealing body and projecting into respective recesses are provided in the leg for effecting a form-locking connection between the slide ring and the annular sealing body.
- the invention overcomes the above-discussed mechanical disadvantages by virtue of the fact that the free axial end surface of the axial leg has recesses which reach from the radially outer surface to the radially inner surface, and the radially inward oriented extensions formed on the trapezoidal sealing body are received in the recesses.
- the trapezoidal sealing body is prevented from shifting in the circumferential direction.
- the recesses are so dimensioned that even in the case of an unavoidable axial twisting of the sealing body, a radially sufficient overlap is preserved to prevent a rotary motion of the sealing body.
- the recesses and the extensions inserted therein serve for transmitting the frictional torques which are generated. In addition to the frictional transmission of the friction torques, the latter are also transmitted by a form fit. A turning of the sealing body relative to the slide ring is thus not possible.
- undercuts may be provided into which the correspondingly shaped extensions of the sealing body may project.
- the axial legs of the slide rings have a radially outward-oriented enlargement at their axially outer end.
- the enlargements serve as supports underneath the sealing bodies to prevent a twisting thereof in the region between the recesses.
- FIG. 1 is a fragmentary axial sectional view of a preferred embodiment of the slide ring seal assembly according to the invention.
- FIG. 2 is a fragmentary radial view of a slide ring structured according to the invention.
- FIG. 3 is a sectional view taken along III—III of FIG. 2 , showing a sealing body in phantom lines.
- FIG. 4 is an enlarged end view of a slide ring leg as viewed in the direction of the arrow IV in FIG. 1 .
- FIG. 1 shows a slide ring seal assembly 1 having cross-sectionally trapezoidal annular sealing bodies 2 , 3 and cross-sectionally angled (L-shaped) slide rings 4 and 5 .
- the slide rings 4 and 5 have axially extending annular legs 6 , 7 .
- the axially extending annular legs 6 , 7 are provided with recesses 10 and 11 which extend from the radially outer circumferential surface 12 to the radially inner circumferential surface 13 of the respective legs 6 , 7 .
- the recesses 10 and 11 further extend axially inward from free axial end surfaces 8 and 9 of the legs 6 , 7 .
- the sealing bodies 2 , 3 have, in the region of the recesses 10 and 11 , radially inward oriented extensions 14 , 15 which are received by the respective recesses 10 and 11 .
- FIG. 2 shows, in the region of the recess 10 , one part of a slide ring 4 according to the invention.
- the leg of the slide ring 4 has, at its axially outer end 20 , a circumferentially extending enlargement 21 and an axially extending undercut 19 is shown in broken lines.
- the recess 10 has an axial end face 30 and two side walls 31 .
- FIG. 3 illustrates the slide ring 4 along the section line III—III to show the recess 10 , the undercut 19 and the radial enlargement 21 .
- the annular sealing body 2 seated on the upper surface 12 of the axial leg 6 is shown in broken lines.
- the radial extension 14 of the sealing body 2 extends into the recess 10 .
- the radial extension 14 further has an axial projection 26 which is received in the undercut 19 .
- FIG. 4 which is a full end view of the slide ring leg 6 , illustrates the enlargement 21 and further shows, in an exemplary manner, four circumferentially uniformly distributed recesses 10 , each continuing with an axially inward extending undercut 19 .
